D.2 Testing Generator Stator Windings
ATTENTION! Before working on the system read the see “Safety Precautions” on page 10.
D.2.1 Testing Generator Stator Winding for "Shorts" to Ground
The generator stator windings can be tested as follows:
1. Ensure that the generator is "OFF" and cannot be accidentally started. Disconnect the battery.
2. Remove the cover of the power treminal box.
3. All terminal box connections are to be removed. (See appropriate circuit diagram.)
4. Remove all cables.
5. A check of the power terminal box is made by means of a multimeter to determine whether
there is continuity between the individual windings connections.
If continuity is detected for any of the combinations, the generator must be sent to the factory for
inspection and repair. If this is not possible, the stator can be rewound by a qualified tradesper-
son/technician. Winding diagrams can be obtained from Fischer Panda GmbH, Germany.
This test, unfortunately, is carried out at very low voltage (9V) when a normal multimeter is used.
Therefore only positive short circuits will be displayed. There is the possibility that a short circuit
will occur in spite of a negative test result (i.e. moisture). A reliable check can only be carried by
using an essentially higher voltage (approx 500V). This type of measuring instrument is normally
only used by experts.
If in doubt an electrician must check the winding for a short circuit with an isolation meter.
